From earlier *xesternos (to differentiate it from a later form *hortos if the shift */x/ > */h/ in the Italic languages already happened during late Proto-Italic). From Proto-Indo-European *dʰǵʰyésteros + *-nos (the earlier version in Proto-Italic is generated by the apheresis of dʰ-, otherwise it would be **θesternos, but the regular development is x > h, hence Latin hesternus).
Cognate with English yester- (cf. yesterday), German gestern (cf. Gestern) and Dutch gisteren.
